Figure 1
Figure 1 A 55-year-old woman with occlusive cancer in the upper rectum and a 17-mm synchronous cancer in the sigmoid colon. A-C: Colonoscopic (A), three-dimensional endoluminal computed tomographic (CT) colonographic (i.e., virtual colonoscopic) (B), and three-dimensional volume-rendered (C) images of the colon show a luminal-encircling occlusive mass (arrowheads) in the upper rectum that impeded the passage of a colonoscope; D, E: Three-dimensional endoluminal (D) and two-dimensional sagittal (E) CT colonographic images show a 17-mm polyp (arrowheads) unassociated with invasive features in the sigmoid colon. The lesion was removed by surgery and pathologically confirmed as a cancer confined to the mucosa.

Figure 2 A 79-year-old man with a 9-mm inflammatory polyp at ileocolic anastomosis. Three-dimensional endoluminal (A) and two-dimensional coronal (B; I = Ileum and C = Colon) computed tomographic colonographic images and a colonoscopy image (C) obtained 3 years after colorectal cancer resection show a well-defined sessile polypoid lesion (arrowheads) at the anastomotic line. Colonoscopic biopsy revealed nonspecific chronic inflammation with edema and no evidence of tumor recurrence.

Figure 3 A 66-year-old man with a 16-mm ulcerating anastomotic recurrence. Three-dimensional endoluminal computed tomographic colonographic (A; U = Ulcer) and colonoscopic (B; U = Ulcer) images obtained 10 mo after cancer resection surgery show an ill-defined elevated lesion with central ulceration (arrowheads) at the anastomosis site. Subsequent surgical resection and pathologic analysis confirmed recurrent adenocarcinoma (reprint with permission[68]).
